| Feb 20, 2025 | Lone Star Texas Grill (930 Dixon Rd, Toronto, Ontario) | TAC Ontario Chapter Talk - February 2025 Topic: Overview of Available Products for the Support of Underground Construction with an Emphasis on Temporary SOE Date: Thursday, February 20, 2025 Presenter: Andrew King, P.E., S.E. Location: Lone Star Texas Grill (930 Dixon Rd, Toronto, Ontario) Time: 5:30 p.m. (Registration) 6:00 p.m. (Presentation) Registration Cost: $10 - TAC Members $20 - Non-members $10 - Government Employees Presentation Overview: Many types of products are available to support underground excavations and each product serves a different purpose and/or situation. This presentation will cover the more common products available on the market today and go through their individual uses. This presentation will cover some of the more specific design aspects as well. Speaker Bio: Mr. King has 18 years of structural engineering experience dealing with structures of various types, sizes and intended uses. These structures have been constructed with a variety of materials including steel, wood, concrete and aluminum and have been employed both above and below ground. Mr. King has spent the last 12 years designing support of excavation structures utilizing rolled steel beams and plates, often combined with timber. The vast majority of these structures are temporary, but several have been final, long-term structures. Design efforts have included dozens of projects across North America and Central America. Projects of note include: I-265, Drumanard Tunnel, Prospect, KY Eastside Interceptor, Richmond, IN Gateway National Park, St. Louis, MO NEORSD Sewer Program, Cleveland, OH Ontario LRT, Ontario, Canada Armstrong Coal, Survant Slope, Center City, KY Kennecott Copper, Rio Tinto, Salt Lake City, UT OARS, Columbus, OH SAWS Project, San Antonio, TX Val Vista Water Transmission, Mesa, AZ DC Clean Waters, Washington, DC Integrated Pipeline, Dallas, TX 2400 mm Trunk Sewer, Mid-Halton, Canada Tijuana Water Tunnel, Tijuana, Mexico LRL Tunnel, Dillsboro, NC Kaneohe-Kallua Tunnel, Honolulu, HI Hamilton Interceptor, Hamilton, OH Keller Pedestrian Tunnel, Keller, TX | Contact onttac@gmail.com Registration Link |
| Feb 25, 2025 | Virtual (hosted through MS Teams) | TACym Tunnelling 101 Webinar: An Introduction to Excavation-induced Settlement Analysis and Impact Assessment Topic: An Introduction to Excavation-induced Settlement Analysis and Impact Assessment Abstract: Tunneling in urbanized areas poses significant challenges due to the potential impacts on existing nearby assets. Conducting construction impact assessments is essential in tunnel design to understand these impacts and develop effective mitigation strategies. Impact assessments cover a wide range of topics, including estimating surface and subsurface ground movements, complex modeling of ground relaxation, soil-structure interaction, and structural behavior under tunnel-induced deformations. Beyond traditional deterministic analysis, probabilistic risk assessment can be utilized to address the various uncertainties in design and analysis. The integration of digital techniques and automation tools can significantly enhance the speed and accuracy of the design workflow. Speaker Bio: Roham Akbarian, P.Eng., M.A.Sc., M.Sc., Tunnelling Engineer, Arup Roham Akbarian is a tunnelling engineer with Arup. He has worked as a property protection engineer on major infrastructure projects in Canada and the US. With a background in underground engineering, he holds a master’s degree in Civil Engineering from McMaster University, where his research focused on risk management in urban underground construction. He also earned a master’s degree in Civil Engineering for Risk Mitigation from the Polytechnic University of Milan, where his research centered on geotechnical risk assessment. Roham’s expertise includes tunnel-induced impact assessment, settlement analysis, numerical modeling, probabilistic risk assessment, reliability analysis, and the use of digital techniques in underground engineering. He has published numerous articles on these topics at various international conferences. | Contact info@tunnelcanada.ca Registration Link |
